Jurassic Period

The Jurassic Period is the second period of the Mesozoic Era, lasting from approximately 201 to 145 million years ago. It is named after the Jura Mountains, where limestone strata from the period were first identified.

Geology

During the Jurassic Period, the supercontinent Pangaea began to break apart, leading to the formation of the Atlantic Ocean. This period saw widespread volcanic activity, leading to the formation of new mountain ranges and the release of carbon dioxide into the atmosphere.

Climate

The climate during the Jurassic Period was generally warm and humid, with lush vegetation covering the land. The sea levels were high, leading to widespread shallow seas and the formation of coral reefs. The high levels of carbon dioxide in the atmosphere contributed to the warm climate.

Flora and Fauna

The Jurassic Period is known for the dominance of dinosaurs, including iconic species such as Stegosaurus, Brachiosaurus, and Allosaurus. The first birds and mammals also appeared during this period. The vegetation included ferns, cycads, and conifers, and the first flowering plants began to emerge towards the end of the period.
